Subnode Format
==============
-The required properties of child nodes are (as defined in pinctrl-bindings):
-- function
-- groups
+The required properties of pinmux child nodes are:
+- function: the mux function to select
+- groups : the list of groups to select with this function
-Each function has only one associated pin group. Each group is named by its
-function. The following values for the function and groups properties are
-supported:
+Required properties of pinconf child nodes are:
+- groups: A list of groups to select (either this or "pins" must be
+ specified)
+- pins : A list of ball names as strings, eg "D14" (either this or "groups"
+ must be specified)
+
+Optional properties of pinconf child nodes are:
+- bias-disable : disable any pin bias
+- bias-pull-down: pull down the pin
+- drive-strength: sink or source at most X mA
+
+Definitions are as specified in
+Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt, with any
+further limitations as described above.
